ABSTRACT
The slurry is prepared as an intermediate product and then dried to be the final product. Since in the shaping process slurry must have fluidity, the viscosity measurement is very important to characterize the slurry. Dense slurry is able to become a liquid or solid state even though the particle concentration of the slurry is not changed. Because particles in the slurry make an assembling structure depending on the inter-particle force. The rotational viscometer of a single cylinder and the vibrating viscometer are often used for slurry characterization, in spite of the fact that they are allowed to use only Newtonian fluids. The descending rate of the settling hydrostatic pressure depends on the assembling structure in slurry. The prepared slurry is usually characterized with an apparent viscosity, because its measurement time is shorter than that of a settling test and hydrostatic pressure, and in many cases they are corresponding with each other.
